Process Firstly,raw material is crushed by jaw crusher to the size required,then elevated into a hopper from which the material is transported through the electro magnetic vibrating feeder evenly and continuously into the grinding chamber for powder processing.The rollers oscillate outward to press the ring because of the centrifugal force and the shovel scoops up the materials, send to the
Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.
